About IronCurtain – Block What Ad Blockers Miss

You know the sites. You click play, and three tabs open. You close them, and a full-screen overlay asks you to spin a wheel. You close that, and the page won't scroll. IronCurtain makes all of that disappear. BUILT FOR THE WORST OF THE WEB Some sites are aggressive. Popups on every click. Invisible layers hijacking your taps. Fake download buttons. Redirects the moment you look away. IronCurtain was designed specifically for these environments — the places where regular ad blockers aren't enough. Install it. Go to your favorite site. Press play. That's it. WHAT IT BLOCKS - Pop-ups and pop-unders that open on click or on load - Full-page overlays, interstitials, and "wait" screens - Invisible click-hijacking layers covering the player... or the page - Scroll-locking that freezes your browser - Redirect loops and back-button traps - Ad scripts from 25+ known networks - Fake countdown timers and "continue" pages HOW IT WORKS IronCurtain runs at three levels so nothing slips through: 1. Network level — Blocks requests to known ad domains before they even load. Zero performance hit. 2. Script level — Intercepts the actual JavaScript calls that trigger popups, pop-unders, and redirects. Runs inside the page context where ad scripts live. 3. DOM level — Detects and removes overlay elements in real time. If a site locks your scroll, IronCurtain unlocks it automatically. YOUR PRIVACY - Anonymous usage analytics only (block counts by category — no URLs, no personal data) - You can opt out of analytics with one click in the popup - No browsing history, no page content, no tracking - Issue reports are voluntary and user-initiated FEATURES - Works on all sites, all pages, all iframes - Per-site whitelist for sites that behave - Live block counter so you can see what was stopped - One-click on/off toggle - Lightweight — no performance impact on your browsing WHY IRONCURTAIN? Your regular ad blocker handles banners, pre-rolls, and tracker scripts. IronCurtain handles everything else — the aggressive, in-your-face tactics that only show up on certain kinds of sites. You know the ones. Install it. You'll notice the difference on your first click.
